the fixing frame is characterized in that a guide rod is fixedly arranged below the fixing frame and inserted into a guide hole of the support frame, an adjusting screw rod is fixedly arranged on the support frame, and the fixing frame is connected with the upper end of the adjusting screw rod in a vertically lifting mode.

The beneficial technical effect that this scheme produced is:

the clamping part is inserted into the left sleeve and the right sleeve, so that when an animal is fixed, the clamping part can be clamped at the head of the animal and then inserted into the left sleeve and the right sleeve, the use is convenient, and the trouble that the head of a large animal is difficult to push into the clamping part and then fix when the clamping part is fixedly arranged on the support is avoided;

the driving device is arranged to drive the clamping part to clamp or loosen the head of the animal, so that the use is more convenient;

through setting up adjusting screw and guide bar for the mount is fixed on the support frame with adjusting from top to bottom, thereby makes the highly adjustable on the relative ground of clamping part, can fix the animal of multiple size height.

According to the embodiment of the invention, the following further technical solutions are provided:

furthermore, two adjusting nuts are arranged at the upper end of the adjusting screw rod, and the fixing frame is clamped and fixed at the upper end of the adjusting screw rod by the two adjusting nuts.

Furthermore, the support frame is also provided with a fixing hole.

Further, the lower end of the left clamping rod is connected with the upper end of the left sleeve through a bolt.

Typically, the drive means is an electric cylinder.

Typically, the drive means is a pneumatic cylinder.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1-2, a head fixing device for an explosive injury animal comprises a fixed frame 1, a supporting frame 2, a sliding rod 7, a sliding block 8, a driving device 6 and a clamping part; the clamping part comprises a left clamping rod 92, a right clamping rod 91, a left sleeve pipe 10 and a right sleeve pipe 11, the upper end of the left clamping rod 92 is hinged with the upper end of the right clamping rod 91, and the middle parts of the left clamping rod 92 and the right clamping rod 91 are bent outwards to form the clamping frame 9. When large animals such as pigs, sheep and the like are fixed, the animals are pushed to the position before the fixation and the heads of the animals extend into the clamping frame 9 by using very labor because the animals struggle; since the clamping frame 9 can be taken down from the fixing frame 1, the clamping frame 9 is clamped on the head of the animal and then the clamping frame 9 is connected to the fixing frame 1 more conveniently. The lower end of the left clamping rod 92 is inserted into the opening 101 of the upper end of the left sleeve 10, and the lower end of the right clamping rod 91 is inserted into the central hole 111 of the upper end of the right sleeve 11.

As shown in fig. 1, a sliding rod 7 is welded on a fixed frame 1, a sliding block 8 is slidably arranged on the sliding rod 7 along the sliding rod 7, the sliding rod 7 can be generally arranged to be a square section rod, and the sliding block 8 is sleeved on the sliding rod 7 through a square hole, so that the clamping frame 9 is better in stability and is not easy to overturn. As shown in fig. 2, the driving device 6 is fixedly disposed on the sliding rod 7, the driving device 6 drives the sliding block 8 to move along the sliding rod 7, the left sleeve 10 is fixedly disposed on the sliding rod 7, the right sleeve 11 is provided with a sliding groove 113, a fixing pin 112 capable of sliding along the sliding groove 113 is disposed in the sliding groove 113, and the fixing pin 112 is fixed on the sliding block 8. Thus, when the slide block 8 moves left and right, the right clamping rod 91 rotates around the upper end, and the right clamping rod 91 and the right sleeve 11 cannot be blocked.

Two guide rods 3 are fixedly arranged below the fixing frame 1, the two guide rods 3 are inserted into guide holes 22 of the support frame 2, adjusting screws 4 are welded on the support frame 2, and the fixing frame 1 can be connected with the upper ends of the adjusting screws 4 in an up-and-down lifting mode. The guide rod 3 plays a role in guiding up and down movement, and the height of the clamping frame 9 is adjusted by adjusting the height of the fixing frame 1.

Furthermore, two adjusting nuts 5 are arranged at the upper end of the adjusting screw rod 4, the upper end of the adjusting screw rod 4 penetrates through the fixing frame 1, and the fixing frame 1 is clamped and fixed at the upper end of the adjusting screw rod 4 through the two adjusting nuts 5. In this way, the holder 1 can be adjusted to a suitable height by screwing the two adjusting nuts 5.

In order to fix the support frame 2 on the ground or a work bench, the support frame 2 is provided with a fixing hole 21.

In order to prevent the animal from struggling to pull the holder 9 out of the holder 1, the lower end of the left clamping rod 92 is bolted to the upper end of the left sleeve 10.

Generally, the driving device 6 can be an electric cylinder or an air cylinder.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
