[0021] Examples, such as Figure 1 and Figure 2 As shown, the utility model provides a cable reel vehicle brake fixing device, including a pin shaft 1, a shoulder is provided on the pin shaft 1 and a spring 2 is sleeved on the shoulder, the end of the pin shaft 1 close to the shoulder is used to cooperate with the brake groove set on the cable reel, the end of the pin shaft 1 away from the shoulder is provided with a brake seat 3, the center of the brake seat 3 is provided with a sleeve 31 interlaced with the pin shaft 1, the end of the sleeve 31 away from the back spring 2 is provided with a first inclined surface 32, a brake handle 4 is provided on the brake seat 3, the brake handle 4 includes a handle 41 and a handle sleeve 42, the end of the handle sleeve 42 facing the sleeve 31 is a second inclined surface 43, the highest point and the lowest point of the first inclined surface 32 are respectively provided with a first clamping groove 33 and a second clamping groove 34, the second inclined surface 43 is provided with a clamping protrusion 44 cooperating with the first clamping groove 33 and the second clamping groove 34, and a radial screw 5 is provided on the handle sleeve 42, which is connected to the screw hole 11 set at the end of the pin shaft 1. Specifically, by rotating the brake handle 4, the wedging surfaces of the handle sleeve 42 and the shaft sleeve 31 can generate relative movement, and the locking protrusion 44 can be locked in the first locking groove 33 and the second locking groove 34 at different distances to change the axial position of the pin 1. For example, when the locking protrusion 44 is locked in the first locking groove 33 at the highest point of the inclined surface, the combined length of the first inclined surface 32 and the second inclined surface 43 is the largest, and the pin 1 is actually braked by the brake handle 4. When the locking protrusion 44 is locked in the second locking groove 34 at the lowest point of the inclined surface, the first inclined surface 32 and the second inclined surface 43 basically match each other, the combined length is the shortest, and the pin 1 is actually inserted into the brake groove of the cable reel, so braking can be achieved, and the pin 1 can obtain a certain preload force under the action of the spring 2 to ensure the automatic effect. The device has a reasonable design, a simple structure, is easy to operate, and has good braking instantaneity and strong practicality.

[0022] To improve the practicality of the brake seat 3, the brake seat 3 provided by the present invention includes an end plate 35, which is provided with a radial plate 36 integral with the shaft sleeve 31. Connecting posts 37 are provided at both ends of the radial plate, and the centers of the connecting posts 37 are used to install screws. The end plate can be matched with a cable reel bracket, which can be the bracket of the entire cable reel cart or a bracket that directly contacts the cable reel. Screws inserted into the connecting posts can secure the brake seat 3 to the bracket, ensuring that the braking path of the device is in a relatively fixed position, thereby improving the efficiency of manual braking.

[0023] Furthermore, the end plate adopts an elliptical structure, which can ensure that the brake seat and the cable reel have a relatively large contact area, and the screws at both ends can also obtain a large connection span, thereby realizing the braking of the cable reel by the device.

[0024] In order to facilitate the operation of the handle 41, the present invention designs the handle 41 to be a flat structure, and a plurality of wear-resistant protrusions 45 are provided on the surface of the handle 41, which can play an anti-slip role.
