[0006] The pusher body 2 includes a pusher arm 13, a connecting arm 14, and a body 15; the connecting arm 14 is connected to the body 15; the front part of the body 15 is connected to one end of each of the two pusher arms 13, forming a tree-branch shape; the middle parts of the two pusher arms are connected as one unit; the front part of the body 15 has a threaded hole for installing the buffer pad 3 inside the guide rail; the upper and lower sides of the body 15 have shaft holes for installing the roller assembly 5; the middle part of the body 15 has a hole for installing a hook of the tension spring 6; the connecting arm 14 has a light hole for connecting the power transmission mechanism; the pusher body 2 is connected to the power transmission mechanism through the lower hinge hole.

[0007] Both ends of the tension spring 6 are hooks. One hook is installed on the pin 7, and the other hook is installed on the hole in the middle of the pusher body 2, with the hole being close to the end of the body 15.

[0008] The right guide rail 11 is provided with a right guide rail boss 12, which contacts the limiting block 4 to prevent it from rotating.

[0009] The roller assembly 5 includes 4 sets of rollers.

[0010] The beneficial effects of this utility model are as follows: This compact pusher features a simple design, reliable operation, light weight, and small size. It utilizes a box-type guide rail and rollers to achieve rapid reciprocating motion, and employs a tension spring to achieve rapid pushing and resetting, thus fulfilling the requirement of a compact structure and small footprint for the pushing device.

[0016] This compact pushing device mainly consists of a box-type guide rail 1, a pusher body 2, a buffer pad 3, a limiting block 4, a roller assembly 5, a tension spring 6, and connecting parts. The pusher body 2 is installed inside the box-type guide rail 1, and the two ends of the tension spring 6 are respectively hung on the box-type guide rail 1 and the pusher body 2. The limiting block 4 is installed at the front of the box-type guide rail 1, and the buffer pad 3 is installed on the pusher body 2 to provide cushioning when the pusher body 2 quickly resets.

[0017] The box-type guide rail 1 provides support, guidance, and positioning for the pusher body 2. The box-type guide rail 1 consists of a left guide rail 10 and a right guide rail 11, which are fixed together with bolts and locating pins. A through hole at the rear of the box-type guide rail 1 is used to install a pin, which is used to install one hook of the tension spring 6. The other hook of the tension spring 6 is installed on a hole in the pusher body 2. A hole at the front of the box-type guide rail 1 is used to install a limiting block 4, which determines the initial position of the pusher body 2. A boss is provided behind the hole at the front of the right guide rail 11 to restrict the rotation of the limiting block 4.

[0018] The pusher body 2 is equipped with four sets of rollers, which cooperate with the guide rail of the box-type guide rail 1 to enable reliable reciprocating motion of the pusher body 2 within the box-type guide rail 1. The pusher body 2 is connected to the power transmission mechanism through the lower hinge hole. When pushing, the power transmission mechanism drives the pusher body 2 to move forward along the box-type guide rail 1 until the maximum stroke is reached. At this time, the tension spring 6 is stretched. When the pushing action is completed, after the intermittent driving power disappears, the pusher quickly returns to the initial position under the action of the tension spring 6.

[0019] The pusher body 2 is characterized by two pushing arms 13 at the front for pushing objects; the rear part of the pusher body 2 is characterized by a body 15, with a threaded hole at the front for mounting a buffer pad, and four shaft holes on the upper and lower sides for mounting roller assemblies. There is a hole in the middle of the body for mounting a hook for a reset spring. The lower rear part of the pusher body 2 is characterized by a connecting arm 14 with a light hole for connecting a power transmission mechanism.
