[0038] The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0039] Referring to Figures 1-5 , a control lever device for a vehicle includes: a main body rod 100, a handle 101, a limit groove 102, a clamping strip 103, a clamping groove 104, and a clamping block 105. The main body rod 100 has a sleeve 106 and a rod body 107 inserted into the sleeve 106. The length of the main body rod 100 is adjusted by sliding the rod body 107 in the sleeve 106. Two limit grooves 102 are provided on the rod body 107 and are located on both sides of the axis of the rod body 107. A clamping strip 103 is disposed in the limit groove 102, and a cylindrical portion 108 rotatably connected to the side wall of the limit groove 102 is provided on the clamping strip 103, so that the clamping strip 103 rotates in the limit groove 102. A clamping block 105 is fixedly provided at one end of the clamping strip 103, and one end of the clamping block 105 penetrates out of the limit groove 102. A button 109 penetrating out of the limit groove 102 is fixedly connected to the clamping strip 103, and the button 109 is located between the cylindrical portion 108 and the clamping block 105. Two groups of clamping grooves 104 are arranged along the axial direction on the inner wall of the sleeve 106, and the clamping grooves 104 are located at positions opposite to the limit grooves 102. A first spring 120 is disposed in the limit groove 102, and both ends of the first spring 120 respectively abut against the clamping strip 103 and the side wall of the limit groove 102. The clamping block 105 is embedded into the clamping groove 104 under the action of the first spring 120, thereby limiting the rod body 107.

[0040] One end of the main body rod 100 passes through the sleeve 106 and is fixedly connected with an installation part 111. Two adaptation parts 112 are arranged on both sides of the installation part 111. A guiding column 113 is fixedly arranged at the central position of the installation part 111. A guiding groove 114 for accommodating the guiding column 113 to be embedded is arranged on the adaptation part 112. The guiding groove 114 has an arc surface that fits the side surface of the guiding column 113 and also has an opening for the guiding column 113 to pass through. The guiding column 113 is embedded into the guiding groove 114 through the opening.

[0041] In one embodiment, two sliding grooves 115 are formed on the installation part 111. A limiting plate 116 is slidably connected in the sliding grooves 115. A plurality of limiting pins 117 are circumferentially and fixedly connected to the limiting plate 116. A limiting hole 118 for the limiting pins 117 to be inserted is formed on the installation part 111. Positioning holes 119 for the limiting pins 117 to pass through are formed on both of the two adaptation parts 112. By moving the limiting plate 116, the limiting pins 117 pass through the positioning holes 119 and are inserted into the limiting holes 118 to limit the adaptation part 112. A second spring 121 is arranged in the limiting groove 102. Two ends of the second spring 121 respectively abut against the limiting plate 116 and the inner wall of the sliding groove 115.

[0042] A pressing part 122 is slidably arranged on the installation part 111. The pressing part 122 has a supporting protrusion 123 with one end inserted into the sliding groove 115. The supporting protrusion 123 has an inclined surface that abuts against the limiting plate 116. By the pressing part 122, the supporting protrusion 123 slides in the sliding groove 115, and the inclined surface of the supporting protrusion 123 abuts against the limiting plate 116, thereby driving the limiting plate 116 to move, so that the limiting pins 117 are disengaged from the positioning holes 119 and the limiting holes 118 and no longer limit the adaptation part 112.

[0043] A contact part 124 corresponding to the inclined surface on the supporting protrusion 123 is arranged on the limiting plate 116.

[0044] Two installation plates 125 are fixed on the two adaptation parts 112. The handle 101 is fixed on the installation plate 125 by screws.

[0045] When the handle 101 needs to be replaced, pressure is applied to the pressing part 122, so that the inclined surface of the supporting protrusion 123 contacts the limiting plate 116, and the limiting pins 117 are disengaged from the positioning holes 119 and the limiting holes 118 and no longer limit the adaptation part 112. At this time, the adaptation part 112 can be disengaged from the guiding column 113, so that the handle 101 can be removed. When the angle of the handle 101 needs to be adjusted, pressure is applied to the pressing part 122, and the limiting pins 117 no longer limit the adaptation part 112. At this time, the handle 101 can be rotated. When pressure is no longer applied to the pressing part 122, the limiting pins 117 pass through the positioning holes 119 again and are inserted into the limiting holes 118 to limit the handle 101.

[0046] When it is necessary to adjust the length of the main rod 100, by pressing the button 109, the clamping strip 103 rotates around the cylindrical portion 108, so that the clamping block 105 disengages from the clamping groove 104, enabling the rod body 107 to slide relative to the sleeve 106, thereby adjusting the length of the main rod 100.

[0047] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
