For example, the main body 201 is provided with extending portions 301 extending from two sides thereof, and each extending portion 301 is connected to a corresponding connecting portion 203. For example, the length direction of the main body 201 and the length direction of the extension portion 301 have a predetermined angle therebetween. For example, the predetermined included angle is 85 degrees. Thus, after the connecting portion 203 is connected with the base 102, when a user holds the armrest portion 202, the force is transmitted to the base 102 through the two connecting portions 203, and since a preset included angle is formed between the length direction of the main body portion 201 and the length direction of the extending portion 301 and is 85 degrees, component forces of the two connecting portions 203 are opposite, that is, the two connecting portions 203 have a tendency of being relatively close, on one hand, the stability of connection between the two connecting portions 203 and the base 102 is enhanced, and on the other hand, most of the force applied to the main body portion 201 by the user is transmitted to the base 102, so that labor is saved, and the force application effect is remarkable.

To connect the base 102, for example, the connecting portion 203 has a cylindrical structure; as another example, the connection portion 203 has a circular cross-section. For example, an end of the connecting portion 203 away from the main body portion 201 is provided with an external thread to achieve a detachable connection, such as a screw connection, with the base 102 through the end having the external thread.

In one embodiment, the main body 201 is detachably connected to the two connecting portions 203. For example, the extension 301 is provided with a force receiving projection 302.

For another example, the slot has an internal thread, and the end of the extension 301 is provided with an external thread, so that the end of the extension 301 is screwed into the slot.

In order to facilitate the user to hold the armrest portion 202, for example, a holding space 204 is provided between the main body portion 201 and the armrest portion 202. For example, the grip space 204 has an arc-shaped cross section. In this embodiment, the holding space 204 has an 1/2-oval cross-section. Further, for example, the armrest portion 202 has an arc-shaped cross section. For example, the two ends of the armrest 202 are connected to the two extending portions 301. In this way, the width of the holding space 204 formed between the main body 201 and the armrest 202 corresponds to the width of the hand of the user, and is suitable for the hand of the user to hold.

After the body 101 is connected to the base 102, since the connecting portion 203 has sufficient rigidity, the probability of fracture of the connecting portion 203 is small, and at this time, in order to further improve the force application effect, as shown in fig. 11, it is a schematic structural diagram of the connecting portion 203 in an embodiment, in this embodiment, the connecting portion 203 is sequentially provided with a first adjusting notch 401, a second adjusting notch 402, a third adjusting notch 403, and a fourth adjusting notch 404 from an end portion having an external thread toward the main body portion 201. The connecting portion 203 is provided with a first adjusting notch 401, a second adjusting notch 402, a third adjusting notch 403 and a fourth adjusting notch 404. So, adjust breach 401, second through first regulation breach 402, third regulation breach 403 and fourth regulation breach 404 and can improve the deformation degree of connecting portion 203, increase the elastic deformation of connecting portion 203 for the user is at the application of force in-process, and connecting portion 203 has the elastic deformation of buffering, in order to do benefit to the user and grip, thereby has improved the application of force effect.

For example, the first adjustment notch 401, the second adjustment notch 402, the third adjustment notch 403, and the fourth adjustment notch 404 are spaced apart from each other to avoid affecting the overall rigidity of the connecting portion 203. For example, the opening directions of the first adjusting notch 401, the second adjusting notch 402, the third adjusting notch 403 and the fourth adjusting notch 404 are the same, and the opening directions of the first adjusting notch 401, the second adjusting notch 402, the third adjusting notch 403 and the fourth adjusting notch 404 of the two connecting portions 203 are opposite, and because the two connecting portions 203 have a tendency of relatively closing, the opening directions of the adjusting notches are set so that the component forces of the two connecting portions 203 are opposite but the resultant force is upward, that is, the resultant force is along the length direction of the connecting portion 203, thereby preventing the connecting portions from being broken in the process of applying force.

Further, since the first adjustment notch 401 is close to the end of the connecting portion 203 connected to the base 102, it is stressed that the opening area cannot be too large, for example, the first adjustment notch 401 has a cross section of 1/5 semicircle, and the depth value of the first adjustment notch 401 is smaller than the radius value of the connecting portion 203. Thus, the area of the opening of the first adjusting notch 401 is properly set, so that the elastic deformation of the connecting portion 203 can be increased, and the connecting portion is prevented from being broken in the force application process.

Further, since the second adjustment notch 402 and the third adjustment notch 403 are located in the middle region of the entire connecting portion 203, in order to increase the elastic deformation of the connecting portion 203, the opening areas of the second adjustment notch 402 and the third adjustment notch 403 should be increased correspondingly, and this embodiment achieves increasing the elastic deformation in this region by appropriately reducing the rigidity in this region. For example, the second adjustment notch 402 has a half-heart shaped cross section, and the depth value of the second adjustment notch 402 is equal to the radius value of the connection portion 203. For example, the third adjustment notch 403 has a drop-shaped cross section, and the depth value of the third adjustment notch 403 is equal to the radius value of the connecting portion 203. Thus, the area of the opening formed by the second adjusting notch 402 and the third adjusting notch 403 can increase the elastic deformation of the connecting portion 203, and the connecting portion is not broken during the force application process.

Further, since the fourth adjustment notch 404 is close to the end of the connecting portion 203 connected to the main body portion 201, it is stressed greatly, and the opening area cannot be too large, for example, the fourth adjustment notch 404 has a right triangle cross section, and the depth value of the fourth adjustment notch 404 is smaller than the radius value of the connecting portion 203. Thus, the opening area of the fourth adjusting notch 404 is set to be suitable, so that the elastic deformation of the connecting portion 203 can be increased, and the connecting portion is prevented from being broken in the force application process.

Referring to fig. 12, which is a schematic structural diagram of the base 102 in one embodiment, for example, the base 102 includes a mounting plate 206 and four fasteners 207, for example, the mounting plate 206 is a rectangular parallelepiped. For example, the mounting plate 206 is a plate-shaped rectangular parallelepiped. For example, four mounting holes 208 are evenly distributed on the mounting plate 206. For example, four mounting holes 208 and four fasteners 207 are evenly distributed on the mounting plate 206. For example, the fastener 207 is a bolt. For example, the fastener 207 is a rivet.

To facilitate the penetration of the support column 212, for example, a through-hole 209 opens in the central region of the mounting plate 206. For example, the central region of the mounting plate is the center of the mounting plate and the region around the mounting plate, for example, the mounting plate is an axisymmetric pattern and has two symmetry axes, and the center of the mounting plate is the intersection point of the two symmetry axes; in another example, the mounting plate is a centrally symmetric pattern. The area around the center of the mounting plate includes an area shaped like the pattern of the mounting plate, for example, having an area of 10% to 70% of the area of the mounting plate, for example, the center of the center area of the mounting plate coincides with the center of the mounting plate, and/or the area of the center area of the mounting plate is 20% to 60%, for example, 50% of the area of the mounting plate. For example, the mounting plate has a rectangular configuration, the center of the central region of the rectangular configuration of the mounting plate coincides with the center of the rectangular configuration of the mounting plate, and the area of the central region of the rectangular configuration of the mounting plate is 20% to 50%, for example 40%, of the area of the rectangular configuration of the mounting plate. The other central regions and so on. For example, the projection of the support post 212 onto the through-opening 209 is located in the cross-section of the through-opening 209. That is to say, the cross-sectional area of wearing the mouth 209 is greater than the cross-sectional area of support column 212 to make support column 212 can pass wearing the mouth 209, and then pass the breach of stepping down, drive body 101 and exert the effort to the heat dissipation type switch board that door, lid and baffle correspond, make the connection of door, lid and baffle etc. rather than the heat dissipation type switch board itself that corresponds hug closely more.

In order to make the connection between the mounting plate 206 and the external heat dissipation type power distribution cabinet more stable, for example, the mounting plate 206 is provided with four mounting holes 208, each fastener 207 corresponds to one mounting hole 208, and the fastener 207 is connected to the external heat dissipation type power distribution cabinet after penetrating through the mounting holes 208. So correspond four fasteners 207 through four mounting holes 208, make mounting panel 206 and outside heat dissipation type switch board be connected more firmly stably.

For connecting the two connecting portions 203, for example, the mounting board 206 is provided with two connecting positions 210, and each connecting position 210 is correspondingly connected with one connecting portion 203. In this embodiment, the mounting plate 206 is provided with a through hole and a nut is coaxially disposed in the through hole to form the connection position 210. For example, the radius of the through hole is equal to the inner diameter of the nut. Thus, the end of the connecting portion 203 is connected to the nut, and the through hole can be used to adjust the length of the end of the connecting portion 203 screwed into the mounting plate 206, thereby finely adjusting the distance between the body 101 and the base 102. In order to improve the strength of the connection position 210, in the embodiment, the two sides of the mounting plate 206 are integrally provided with the arc-shaped reinforcing parts, so that the strength of the connection position 210 is improved, and the connection position 210 is prevented from being broken by stress.

Please refer to fig. 13, which is a schematic structural diagram of the supporting body 103 in an embodiment, for example, the supporting body 103 includes a limiting block 211, a supporting column 212 and a magnet block 213, the limiting block 211 is connected to the supporting column 212, the supporting column 212 is magnetically connected to the magnet block 213, the magnet block 213 is used to be fixed on the heat dissipation type power distribution cabinet corresponding to the door body, the cover body and the baffle, and the fixed position of the magnet block corresponds to the abdicating notch, so that the supporting column 212 is magnetically connected to the magnet block 213 after passing through the through hole 205, the through hole 209 and the abdicating notch.

For example, the limiting block 211 is located in the holding space 204, the supporting column 212 is slidably disposed through the through hole 205, the axes of the through hole 205, the through hole 209 and the supporting column 212 are located on the same straight line, and the length of the supporting column 212 is smaller than the maximum distance from the main body 201 to the base 102.

Referring to fig. 14, which is a schematic structural view of another perspective of the main body in an embodiment, in order to make the supporting column 212 slidably penetrate through the through opening 205 along a predetermined direction, in combination with fig. 13 and fig. 14, for example, a sliding groove 601 is disposed on a surface of the supporting column 212, and for example, a sliding rail 701 is disposed on an inner wall of the through opening 205. For example, the slide rail 701 is an elongated semicircular protrusion, and the slide groove 601 is an elongated semicircular groove. The semicircular convex strips are embedded in the semicircular concave grooves, so that the supporting columns 212 are slidably arranged through the through holes 205 along a predetermined direction, namely the length direction of the sliding groove 601. Further, the number of the sliding grooves 601 is four, the number of the sliding rails 701 is four, and the sliding grooves 601 and the sliding rails 701 are arranged in a one-to-one correspondence manner, so that the supporting columns 212 penetrate through the through holes 205 in a sliding manner along a predetermined direction.

For example, the stopper 211 is a rectangular parallelepiped. For example, the support posts 212 are elongated block-like structures. For example, the projection of the support post 212 onto the magnet block 213 is located within the cross-section of the magnet block 213. For example, the cross-sectional area of the support column 212 is smaller than that of the magnet block 213, so that the magnetic force generated by the magnet block 213 can completely act on the support column 212 to improve the adsorption effect.

To improve the holding effect, referring to fig. 10 and 14, for example, the armrest portion 202 is formed with a plurality of notches 702, the notches 702 are spaced apart from each other, and the notches 702 are connected to the holding space 204. For example, the notch 702 is semi-circular in shape. In this embodiment, the number of the notches 702 is four. For example, four notches 702 extend along the arcuate bending direction of the armrest portion 202. The four notches 702 correspond to the four fingers of the user, so that when the user grips the handle, each finger of the four fingers is embedded into the corresponding notch 702, and therefore the gripping effect of the user when the handle is used is improved.

Referring to fig. 15, which is a schematic structural view of another perspective of the main body in an embodiment, in order to improve the supporting effect of the supporting post 212, in combination with fig. 9 and fig. 15, for example, the main body portion 201 further has an accommodating groove 801, the through hole 205 is disposed at the bottom of the accommodating groove 801, the accommodating groove 801 is communicated with the holding space 204, and the shape of the accommodating groove 801 is matched with the shape of the limiting block 211. For example, the through hole 205 is opened in the center area of the bottom of the accommodation groove 801. For example, the cross-sectional area of the through port 205 is smaller than the cross-sectional area of the bottom of the accommodation groove 801. In this way, when the user holds the armrest portion 202, due to the existence of the receiving groove 801, the limiting block 211 can be received in the receiving groove 801 without occupying the space of the holding space 204, i.e. without interfering with the user's holding of the armrest portion 202. Meanwhile, when the user's hand is held in the armrest portion 202, the hand can prevent the movement of the stopper 211, thereby improving the supporting effect of the support column 212.
