When push rod 841 is pressed the undermost end by cam 833, card post 813 card is gone into in draw-in groove 8412, locks clip 82 at the open mode, need not open the clip by hand once more when putting into the leather of waiting to dry in the clip 82, only need put into the leather and press down button 853 after the nip and can close clip 82, make clip 82 press from both sides tight leather, reduced the intensity of labour of blowing, and convenient operation is swift, has improved blowing operating efficiency.

In the embodiment of the present application, as shown in fig. 2, the clamping portion of the left clamping piece 821 is provided with a soft rubber 8211; the clamping portion of the right clamping piece 822 is provided with soft rubber 8221. Soft rubber is provided at the clamping portions of the left and right clips 821, 822 to prevent the clips from pinching the leather.

In the embodiment of the application, in order to improve the energy utilization rate, an exhaust fan 4 is arranged below the box body 1; an air duct 3 is connected between the air outlet of the exhaust fan 4 and the air inlet of the air inlet fan 2. The hot air discharged by the exhaust fan 4 circulates to the air inlet of the air inlet and air outlet fan 2 for hot air recycling, so that the energy utilization rate is improved.

In the embodiment of this application, the outside of box 1 is equipped with controller 7, and air inlet fan 2, air exhaust fan 4 and heater 5 all are connected with controller 7 to wind speed and temperature in the control box 1.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
