[0024] See Figures 1 to 6 , the present utility model has a base 1, a speed control grip 2 is detachably provided on the base 1, a pressing block 21 is slidably provided on the speed control grip 2, one end of the pressing block 21 is located outside the speed control grip 2, the other end of the pressing block 21 is located inside the speed control grip 2, and an elastic member 22 for urging the pressing block 21 to slide towards the outside of the speed control grip 2 is provided inside the speed control grip 2; a potentiometer 23 for adjusting the speed of the thruster as the pressing block 21 slides is fixedly provided inside the speed control grip 2, one end of the pressing block 21 located inside the speed control grip 2 forms a transmission fit with the input end of the potentiometer 23 through a transmission assembly 3, and the output end of the potentiometer 23 is electrically connected to an external underwater thruster; the transmission assembly 3 includes a rack 31 fixedly provided at one end of the pressing block 21 located on the speed control grip 2 and a gear 32 fixedly provided on the input end of the potentiometer 23 and meshing with the rack 31, and the input end of the potentiometer 23 forms a transmission fit with the pressing block 21 through the meshing of the gear 32 and the rack 31.

[0025] When the pressing block 21 moves, the rack 31 transmits the moving amount of the pressing block 21 to the gear 32, and the small gear 32 drives the input end of the potentiometer 23 to rotate. The output end of the potentiometer 23 transmits an acceleration signal to the thruster, so as to control the pressing amount of the pressing block 21 to control the rotation amount of the output end of the potentiometer 23, and further control the speed of the thruster, which is convenient and fast.

[0026] On one side of the speed control grip 2 facing the base 1, there is an opening that is in communication with the inside of the speed control grip 2 and allows the pressing block 21 to slide therein. Inside the speed control grip 2, there is also a limiting block 24 for restricting the pressing block 21 on the speed control grip 2. The limiting block 24 is fixedly arranged near the opening. On the pressing block 21, there is also a sliding groove 211 that can form a sliding limiting fit with the limiting block 24. The pressing block 21 is slidably arranged on the speed control grip 2 through the sliding limiting fit between the sliding groove 211 and the limiting block 24. One end of the elastic member 22 acts on the inner wall of the speed control grip 2, and the other end of the elastic member 22 acts on the pressing block 21. The pressing block 21 makes reciprocating slides on the speed control grip 2 under the action of the elastic force of the elastic member 22 and the sliding limiting fit between the limiting block 24 and the sliding.

[0027] When the pressing block 21 is fully pressed into the speed control grip 2, it is in the full-speed state; when the pressing block 21 is not pressed into the speed control grip 2, it is in the initial state. The elastic member 22 can restore the pressing block 21 in the full-speed state to the initial state.

[0028] There are multiple elastic members 22, and each elastic member 22 is a return spring. On the pressing block 21, there are multiple extension rods 212 fixedly arranged corresponding to the elastic members 22 one by one. One end of each elastic member 22 acts on the inner wall of the speed control grip 2, and the other end of each elastic member 22 corresponds to and is sleeved on each extension rod 212 one by one. Through the arrangement of the elastic members 22, after the pressing block 21 is pressed into the speed control grip 2, the elastic members 22 will output elastic force to restore the pressing block 21 to the initial state, so that the rotation amount output by the pressing block 21 to the output end of the potentiometer 23 is gradually reduced.

[0029] There are two elastic members 22 and extension rods 212, and they are arranged corresponding to each other one by one.

[0030] The speed control grip 2 includes a first half-shell 2-1 and a second half-shell 2-2 that can form a plug-in fit with the first half-shell 2-1. After the first half-shell 2-1 and the second half-shell 2-2 are plugged together, a plug 4 is formed. On the base 1, there is a slot 11 for the plug 4 to be inserted into to form a plug-in fit. The speed control grip 2 is detachably installed on the base 1 through the plug-in fit between the plug 4 and the slot 11. Through the plug-in fit between the plug 4 and the slot 11, it can be seen that the speed control grip 2 is taken out from the base 1, and the first half-shell 2-1 and the second half-shell 2-2 are disassembled for repair, maintenance or replacement, which is efficient and convenient.

[0031] The pressing block 21, the elastic member 22, the potentiometer 23 and the limiting block 24 are all arranged on the first half-shell 2-1. The pressing block 21, the elastic member 22 and the potentiometer 23 are restricted on the speed control grip 2 through the plug-in fit between the first half-shell 2-1 and the second half-shell 2-2.

[0032] Inside the speed control grip 2, there is also a guiding block 25. The guiding block 25 is provided with holes through which the extension rod 212 and the elastic member 22 can pass. One end of the elastic member 22 acts on the inner wall of the speed control grip 2. The other end of the elastic member 22 passes through the hole and is sleeved around the extension rod 212. The extension rod 212 is slidably arranged in the hole. The guiding block 25 is fixedly arranged on the second half shell 2-2.

[0033] Inside the first half shell 2-1, there is a space for placing the guiding block 25.

[0034] Under the guiding action of the hole in the guiding block 25, the extension rod 212 can always slide in the same direction, avoiding the situation of sliding misalignment.

[0035] The racks 31 are provided on both the upper and lower sides of the pressing block 21. Each extension rod 212 is located between the racks 31 on the upper and lower sides of the pressing block 21. A potentiometer 23 can be added to the speed control grip 2 as needed, so that one speed control grip 2 controls two thrusters, and at the same time ensures that the speeds of the two thrusters are the same, with wide applicability.

[0036] Working principle of the present utility model: When a finger applies pressure to the pressing block 21, the pressing block 21 will slide towards the inside of the speed control grip 2. The rack 31 on the pressing block 21 will drive the gear 32 to rotate. The gear 32 will drive the input end of the potentiometer 23 to rotate. The output end of the potentiometer 23 transmits an acceleration signal to the thruster. When the finger pressure is slowly released, the two return springs will output elastic force, causing the pressing block 21 to gradually rebound. The rack 31 drives the gear 32 to rotate in the reverse direction. The gear 32 will drive the input end of the potentiometer 23 to rotate in the reverse direction. The output end of the potentiometer 23 transmits a deceleration signal to the thruster until the pressing block 21 completely returns to the initial state.

[0037] The above specific embodiments have further elaborated on the purpose, technical solution and beneficial effects of the present utility model. It should be understood that the above are only specific embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
