In this embodiment, the both ends of the back-locking screw rod 22 are provided with the bearing frame respectively, make things convenient for the installation of back-locking screw rod 22, make things convenient for back-locking screw rod 22 to rotate simultaneously, make the back-locking structure more stable, the life of back-locking structure has been improved, set up the screw thread on the back-locking screw rod 22, transmission slider 23 cover is established on back-locking screw rod 22, and transmission slider 23 and screw thread mutual adaptation, conveniently realize that transmission slider 23 slides under the effect of back-locking screw rod 22 pivoted, the transmission drives back-locking spring bolt 21 and slides.

Further, the housing assembly 1 further includes a mounting groove 14, and the mounting groove 14 is opened at the bottom of the motor 24 of the housing 11.

In this embodiment, the mounting groove 14 is located at the bottom of the motor 24, so that the motor 24 can be conveniently mounted on the housing 11, the motor 24 can work more stably, and the motor 24 can be kept at a normal level and work more stably.

Further, the shell assembly 1 further comprises four limiting columns 18, the limiting columns 18 are fixedly connected with the shell 11, the number of the limiting columns 18 is four, and the limiting columns 18 are located on the periphery of the bearing 33.

In this embodiment, four spacing posts 18 are located around bearing 33 respectively, and the top of spacing post 18 is provided with the thread groove, and the spacing post 18 that leans on top slider 31 both sides can play spacing effect to top slider 31, can effectually prevent that top slider 31 from taking place the skew, is close to two bearing 33 of bearing 33 and the spring bolt 34 junction of unblanking, can play and carry on spacingly to bearing 33 rotational position, prevents that bearing 33 rotation process is too big, breaks away from spring bolt 34 of unblanking.

Furthermore, a first spring groove is formed in the tightening slider 31, the first spring 33 is located in the first spring groove, and the first clamping plate 16 is located between the first spring 33 and the tightening slider 31.

In this embodiment, the first spring 33 is installed in the first spring groove inside the top-tightening slider 31, one end of the first spring 33 is attached to the first clamping plate 16 inside the top-tightening slider 31, the other end of the first spring 33 is tightly pushed in the groove of the top-tightening slider 31, the first clamping plate 16 can limit the top-tightening slider 31, and the first spring 33 can conveniently reset the top-tightening slider 31 in a sliding manner.

Furthermore, a rotating rod groove is formed in the upper surface of the bearing 33, and one end, close to the bearing 33, of the jacking sliding block 31 is in an arrow shape; a clamping groove is formed in one side, close to the bearing 33, of the bearing 33, and an arrow-shaped end of the bearing 33 is matched with the clamping groove.

In this embodiment, the bull stick groove that bearing 33 upper surface was seted up is convenient and outside handle axostylus axostyle block, and the bull stick groove is the square, makes things convenient for the handle to pass through axostylus axostyle rolling bearing 33, and the bearing 33 lateral wall is circular-arc, and the one end that the tight slider 31 in top is close to bearing 33 is the arrow point form, and the convenient draw-in groove block with bearing 33 is fixed, when convenient reseing bearing 33, plays the spacing fixed effect of draw-in groove.

Furthermore, a clamping hook is arranged on one side, close to the unlocking lock tongue 34, of the bearing 33, a clamping plate is arranged on one side, close to the bearing 33, of the unlocking lock tongue 34, and the clamping hook and the clamping plate are attached to each other.

In this embodiment, the hook on the bearing 33 and the unlocking lock tongue 34 are attached to each other, so that when the bearing rotates conveniently, the hook pulls the snap plate to make the unlocking lock tongue 34 contract inwards, so that unlocking is facilitated, and resetting is facilitated, so that the snap plate pulls the snap plate to make the bearing 33 reset.

Further, a second spring groove is formed in the unlocking lock tongue 34, the second spring 35 is located in the second spring groove, and the second catch plate 17 is located between the second spring 35 and the unlocking lock tongue 34; the second spring 35 and the first spring 33 are parallel to each other.

In this embodiment, the second spring 35 is installed in the inside second spring groove of unblanking spring bolt 34, and the one end of second spring 35 and the second cardboard 17 laminating in the unblanking spring bolt 34, the other end and the inslot of unblanking spring bolt 34 tightly push up, and second cardboard 17 can play spacing effect to unblanking spring bolt 34, and second spring 35 can conveniently play the effect that slides and reset to unblanking spring bolt 34.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
