DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example: See Figure 1-5 The utility model provides a technical solution: a universal hand drill socket wrench, comprising an electric drill socket body 1; in order to solve the problem that the existing universal socket is too large and the socket cannot be sleeved on the nut or bolt when there are raised obstacles around the nut or bolt, the electric drill socket body 1 is provided with a socket shell 2, the top of the sleeve shell 2 is provided with a connecting port 3, the bottom of the sleeve shell 2 is provided with a telescopic port 4, the sleeve shell 2 is provided with a sleeve movable groove 5, the sleeve movable groove 5 is installed with an inner column 51 and a limit column 52, the limit column 52 is provided with a sleeve movable groove 5, and the inner column 51 and the limit column 52 are provided with a sleeve movable groove 5. A second spring 53 is sleeved, and a telescopic sleeve 6 is arranged in the sleeve movable groove 5. When in use, the connection port 3 on the sleeve housing 2 is sleeved on the electric drill, and the electric drill sleeve body 1 is aligned with the bolt or nut to be screwed. In the initial state, the telescopic sleeve 6 extends to the outside of the sleeve movable groove 5. According to the size of the bolt or nut, the bolt or nut will be sleeved in the corresponding telescopic sleeve 6. If there are protruding foreign objects around the bolt or nut, the protrusion will cause the redundant telescopic sleeve 6 to shrink into the sleeve movable groove 5, so that the telescopic sleeve 6 can adapt to the protruding foreign objects around the bolt or nut;
[0023] In order to enable the telescopic sleeve 6 to retract into the sleeve movable groove 5, the telescopic sleeve 6 includes a first sliding sleeve 61, which is slidably installed in the sleeve movable groove 5, a second sliding sleeve 62 is slidably installed in the first sliding sleeve 61, and a third sliding cylinder 63 is slidably installed in the second sliding sleeve 62. Limiting holes 64 are provided in the first sliding sleeve 61, the second sliding sleeve 62 and the third sliding cylinder 63. The limiting column 52 is slidably installed in the limiting hole 64, and a first spring 65 is slidably installed in the limiting hole 64. One end of the first spring 65 is installed at the bottom of the limiting column 52, and the other end of the first spring 65 is installed on the inner wall of the limiting hole 64. One end of the second spring 53 is installed at the top of the sleeve movable groove 5, and the other end of the second spring 53 is respectively installed on one side of the first sliding sleeve 61, the second sliding sleeve 62 and the third sliding cylinder 63. The outer surface of the first sliding sleeve 61 fits with the inner wall of the sleeve movable groove 5, the inner wall of the first sliding sleeve 61 fits with the outer surface of the second sliding sleeve 62, the outer surface of the third sliding sleeve 63 fits with the inner wall of the second sliding sleeve 62, and the inner wall of the third sliding sleeve 63 fits with the inner column 51. When in use, the connecting port 3 on the sleeve housing 2 is sleeved on the electric drill, and the electric drill sleeve body 1 is aligned with the bolt or nut to be screwed. In the initial state, under the action of the second spring 53 and the first spring 65, the first sliding sleeve 61, the second sliding sleeve 62 and the third sliding sleeve 63 are all extended to the outside of the sleeve housing 2, and the electric drill sleeve body 1 is pressed on the bolt or nut. According to the size of the bolt or nut, the bolt or nut will be sleeved in the first sliding sleeve 61, the second sliding sleeve 62 or the third sliding sleeve 63. For example, when the nut is sleeved on the third sliding sleeve 63 When the electric drill sleeve body 1 is moved away from the bolt or nut, under the action of the second spring 53 and the first spring 65, the first sleeve 61 and the second sleeve 62 move in the opposite direction along the limiting column 52 and return to the initial position. The telescopic sleeve 6 adapts to the use environment around the bolt or nut, avoiding the problem that the sleeve cannot be connected to the nut and cannot be used in a narrow environment such as when there are protrusions around the nut due to the oversized sleeve size.
[0024] The working principle is as follows: when in use, the connecting port 3 on the sleeve housing 2 is sleeved on the electric drill, and the electric drill sleeve body 1 is aligned with the bolt or nut to be screwed. In the initial state, under the action of the second spring 53 and the first spring 65, the first sliding sleeve 61, the second sliding sleeve 62 and the third sliding cylinder 63 are all extended to the outside of the sleeve housing 2, and the electric drill sleeve body 1 is pressed on the bolt or nut. According to the size of the bolt or nut, the bolt or nut will be sleeved in the first sliding sleeve 61, the second sliding sleeve 62 or the third sliding cylinder 63. For example, when the nut is sleeved in the third sliding cylinder 63, if there are protruding foreign objects around the bolt or nut, the protrusions will cause the first sliding sleeve 61 and the third sliding cylinder 63 on the outside of the third sliding cylinder 63 to be pressed against each other. The second sleeve 62 is compressed into the sleeve movable groove 5 of the sleeve housing 2. At this time, the first sleeve 61 and the second sleeve 62 move along the direction of the limiting column 52, compressing the second spring 53 on the top of the first sleeve 61 and the second sleeve 62 and the first spring 65 in the limiting hole 64. When the electric drill sleeve body 1 is away from the bolt or nut, under the action of the second spring 53 and the first spring 65, the first sleeve 61 and the second sleeve 62 move in the opposite direction along the limiting column 52 and return to the initial position. The telescopic sleeve 6 adapts to the use environment around the bolt or nut, avoiding the problem that the sleeve cannot be connected to the nut and cannot be used in a narrow environment such as a protrusion around the nut due to an oversized sleeve size.
