[0023] The utility model provides Figure 1-5 A wireless remote control handset for industrial equipment is shown, comprising a handset body 1, a rocker 4 arranged at the top of the handset body 1, and stepped holes 5 opened at the four corners of the handset body 1, multiple step holes 5 are longitudinally slidably provided with position-controllable connecting rods 6, the top of the connecting rod 6 is connected to a handset top cover 2 for preventing extrusion, the part of the connecting rod 6 located between the handset body 1 and the handset top cover 2 is sleeved with a spring 7 for shock absorption, the handset top cover 2 is provided with multiple through holes and grooves adapted to the top parts of the handset body 1, the left and right sides of the top of the handset top cover 2 are connected to fixing rings 111, the part of the handset top cover 2 located at the top of the rocker 4 is provided with a circular ring 11 whose circumferential side wall can fit and rotate with the handset top cover 2 and can extend to the inside of the handset top cover 2, the fixing ring 111 is located at the center of the circular ring 11, multiple pull rods 113 are connected to the top of the circular ring 11, the bottom ends of the multiple pull rods 113 are connected to a clamping plate 112, and the top of the clamping plate 112 is rotatably connected to the fixing ring 111.

[0024] When the circular ring 11 rotates, the circular ring 11 drives the pulling rod 113 to pull the clamping plate 112 away from or close to the center of the circle synchronously; when the circumferential side walls of the clamping plate 112 are in contact with the circumferential side walls of the adjacent clamping plates 112, a circular hole for clamping and fixing the rocker 4 appears at the center of the circle; when the circumferential side walls of the clamping plate 112 are away from the circumferential side walls of the adjacent clamping plates 112, the space in the fixing ring 111 can be used for the rocker 4 to rotate; through the arrangement of the circular ring 11, the fixing ring 111, the clamping plate 112 and the pulling rod 113, it is achieved that during the rotation of the circular ring 11, the clamping plate 112 can move away from or close to the center of the circle synchronously, and the clamping function of the rocker 4 is achieved through the synchronous approach of the clamping plate 112, thereby preventing the rocker 4 from being broken during extrusion and impact.

[0025] The top of the ring 11 is connected to a control rod 114 for controlling the rotation of the ring 11. The top cover 2 of the handheld device is provided with an arc groove 201 for the control rod 114 to rotate. Through the setting of the control rod 114 and the arc groove 201, the rotation of the ring 11 can be conveniently controlled, thereby facilitating the clamping of the rocker 4.

[0026] A clamping assembly 3 for controlling the height of the connecting rod 6 is arranged on both sides of the short side of the handheld device top cover 2, and a positioning block 9 for fixing is rotatably arranged at the bottom end of the clamping assembly 3. Through the setting of the positioning block 9, the positioning block 9 is inserted into the positioning groove 10 to prevent the handheld device top cover 2 from closing due to a large impact force, thereby playing a role in limiting the handheld device top cover 2.

[0027] The two side walls of the short side of the handheld device body 1 are provided with steps 8 for the locking assembly 3 to be locked, and the inside of the step 8 is provided with a positioning groove 10 for the positioning block 9 to be inserted. By fitting the locking assembly 3 with the step 8 at different positions, the relative position of the handheld device top cover 2 and the handheld device body 1 is adjusted, thereby realizing the control of the opening and closing of the handheld device top cover 2.

[0028] The stepped hole 5 is located between the handheld device body 1 and the handheld device top cover 2, and a groove for accommodating the spring 7 is provided. The groove is arranged so that when the handheld device body 1 and the handheld device top cover 2 are closed, the spring 7 is accommodated in the groove, so that the handheld device body 1 and the handheld device top cover 2 can fit tightly, ensuring the beautiful appearance and comfort of use.

[0029] The handheld device top cover 2 is made of metal material, which can effectively absorb the squeezing force and the impact force, thereby protecting the handheld device body 1 .

[0030] In the utility model, by setting the connecting rod 6, the spring 7 and the top cover 2 of the handheld device with controllable sliding position, the connecting rod 6 can drive the top cover 2 of the handheld device to slide longitudinally, so that the top cover 2 of the handheld device can be fitted with or separated from the handheld device body 1. When the top cover 2 of the handheld device is separated from the handheld device body 1, the support of the top cover 2 of the handheld device and the shock absorption of the spring 7 can realize the protection of the top parts of the handheld device body 1, thereby reducing the probability of damage to the handheld device body 1. When the top cover 2 of the handheld device is away from the handheld device body 1, the ring 11 rotates counterclockwise to drive the pull rod 113 to pull the clamping plate 112 to achieve the function of limiting and fixing the rocker 4, effectively preventing the rocker 4 from breaking due to extrusion; when the top cover 2 of the handheld device is in contact with the handheld device body 1, the ring 11 rotates clockwise to drive the pull rod 113 to pull the clamping plate 112 away from the fixing ring 111, so that the distance between the fixing rings 111 is enough for the rocker 4 to slide, thereby preventing the top cover 2 of the handheld device from interfering with the normal use of the handheld device body 1.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
