The function of the first spring 202 is to ensure that the clamping block 201 is always in contact with the card slot on the lower template, thereby ensuring the stability of the device. The setting of the first guide rod 203 ensures that the sliding of the clamping block 201 in the fixed rod 1 is smoother, increasing the stability of the device.

[0023] As a technical optimization solution of the utility model, the release mechanism 3 includes a sliding sleeve 301, which is slidingly connected to the fixed rod 1, a connecting rod 302 is fixedly connected to the sliding sleeve 301, a transmission rod 303 is fixedly connected to the connecting rod 302, the connecting rod 302 is slidingly connected to the fixed rod 1, and the transmission rod 303 is slidingly connected to the fixed rod 1. The release mechanism 3 also includes a connecting plate 304, a connecting plate 304 is fixedly installed on the top of the transmission rod 303, and a pull ring 305 is fixedly connected to the connecting plate 304. The setting of the pull ring 305 makes it more labor-saving and convenient to operate the release mechanism 3.

[0024] As a technical optimization solution of the present utility model, the cross section of the end of the clamping block 201 is an arc-shaped structure, and the cross section of the sliding sleeve 301 is a trapezoidal structure.

[0025] As a technical optimization solution of the utility model, a baffle plate 5 is provided on the upper template where the fixing rod 1 is located, an extrusion plate 6 is provided at the bottom of the baffle plate 5, and a clamping mechanism 4 is provided on the extrusion plate 6.

[0026] As a technical optimization solution of the utility model, the locking mechanism 4 includes a mounting block 401, the mounting block 401 is fixedly connected to the extrusion plate 6, two protrusions 402 are slidably connected in the mounting block 401, and the two protrusions 402 are fixedly connected to the rotating shaft 403, and the mounting block 401 is rotatably connected to the center shaft 404, and the center shaft 404 is fixedly connected to two rotating shafts 403, the protrusion 402 and the two rotating shafts 403 on the center shaft 404 are connected by a connecting rod 405, and the connecting rod 405 is rotatably connected to the rotating shaft 403, so that The locking mechanism 4 also includes a second spring 406, and a second spring 406 is fixedly connected between the two protrusions 402 and the mounting block 401. A second guide rod 407 is arranged inside the two second springs 406. The second guide rod 407 is fixedly connected to the mounting block 401, and the second guide rod 407 is slidably connected to the protrusion 402. The function of the second spring 406 is to make the protrusion 402 continuously contact with the baffle 5 to ensure that the extrusion plate 6 is not easy to fall off. The second guide rod 407 ensures that the protrusion 402 slides smoothly in the mounting block 401, thereby increasing the stability of the device.

[0027] As a technical optimization solution of the utility model, the locking mechanism 4 also includes a knob 408, and the knob 408 is fixedly connected to the central axis 404. The knob 408 is rotatably connected to the mounting block 401. The setting of the knob 408 makes it easier and more labor-saving to install and disassemble the extrusion plate 6 when the operating device is installed.

[0028] When the utility model is in use, when the extrusion plate 6 needs to be installed on the baffle 5, first rotate the knob 408 clockwise. The knob 408 drives the central shaft 404 to rotate clockwise, drives the two rotating shafts 403 on the central shaft 404 to rotate clockwise around the central shaft 404, and then drives the connecting rod 405, so that the convex block 402 contracts inward. Then install the extrusion plate 6 onto the baffle 5. Loosen the knob 408, and the convex block 402 will be ejected under the action of the second guide rod 407 and the second spring 406, so that the convex block 402 abuts against the groove on the baffle 5. The second spring 406 will make the convex block 402 continuously abut against the baffle 5 to ensure that the extrusion plate 6 is not easily detached. The second guide rod 407 ensures the smooth sliding of the convex block 402 in the mounting block 401 and increases the stability of the device. When the upper template needs to be installed on the lower template, insert the two fixing rods 1 into the mounting holes on the lower template. The clamping block 201 will be squeezed into the fixing rod 1. When the fixing rod 1 is inserted to the bottom of the lower template, the clamping block 201 will be ejected under the action of the first spring 202 and engage and abut against the card slot on the lower template. The function of the first spring 202 is to ensure that the clamping block 201 always abuts against the card slot on the lower template, so as to ensure the stability of the device. The setting of the first guide rod 203 ensures the smoother sliding of the clamping block 201 in the fixing rod 1 and increases the stability of the device. When the upper template needs to be disassembled, the pull ring 305 at the top of the fixing rod 1 can be lifted simultaneously. The pull ring 305 drives the connecting plate 304, the connecting plate 304 drives the transmission rod 303, the transmission rod 303 drives the connecting rod 302, and then the sliding sleeve 301 at the end of the connecting rod 302 moves upward. The upward movement of the sliding sleeve 301 will squeeze the clamping block 201 to make it retract into the fixing rod 1, and then release the engagement and abutment between the clamping block 201 and the card slot on the lower template, so that the upper template can be easily disassembled, improving the work efficiency.
