The direction handle drum 3 is rotatable about a first horizontal axis (not shown) and the towing handle drum 4 is rotatable about a second horizontal axis (not shown). The first horizontal shaft and the second horizontal shaft are respectively fixed on two supports of a driver controller, and the first horizontal shaft and the second horizontal shaft are not coaxial. The mounting mode of the direction handle drum body 3 and the traction handle drum body 4 on the bracket belongs to the prior art.

A locking rod 7 moving along the horizontal direction is arranged between the traction handle drum body 4 and the direction handle drum body 3, the locking rod 7 comprises a rod body, the left end of the rod body is provided with a roller frame 71, the roller frame 71 is provided with a roller 6, and the rotation axis of the roller 6 is along the vertical direction.

As shown in fig. 4 and 5, the rod body is provided with a rotation stop surface for cooperating with the limiting frame 9 in a rotation stop manner, so as to prevent the rod body from rotating around the axis thereof, and the limiting frame 9 is stationary. The rod body is provided with a square rod 72 and a round rod 73, the right side end part of the round rod 73 forms a locking plug, and the end face of the locking plug is chamfered and is similar to a pin. The outer peripheral surface of the square rod 72 forms the rotation stop surface, and the limiting frame 9 is provided with a square hole corresponding to the square rod 72.

The limiting frame 9 or the support is provided with a guide sleeve 5, the guide sleeve 5 is connected with the limiting frame 9 or not connected with the limiting frame, and the guide sleeve 5 is used for guiding, moving and assembling the round rod 73. In the embodiment shown in fig. 2, 3 or 6, the limiting frame 9 is in a shape of a Chinese character 'ji', and the limiting frame 9 and the guide sleeve 5 are welded and fixed on a side plate of a bracket of the driver controller, which is close to the drum body 4 of the traction handle. When the locking rod 7 moves in its axial direction, i.e. horizontal direction, the guide sleeve 5 guides the movement of the locking rod 7.

The rod body of the locking rod 7 penetrates through the limiting frame 9, and a spring 8 is sleeved on the rod body; the spring 8 is arranged on the square rod 72, and the spring 8 is compressed between the roller frame 71 and the limiting frame 9.

As shown in fig. 2 and 3, a boss 31 is provided on the right side of the drum body 3, the boss 31 has a top and a slope surface located on the front and rear sides of the top, and the slope surface may be an inclined surface or an arc surface. Specifically, the boss 31 is of a herringbone structure with a low front and back part and a high middle part, and the top part of the herringbone structure is provided with an arc surface matched with the periphery of the roller 6. When the direction handle 1 is at the '0' position, the top of the boss 31 is pressed and matched with the roller 6. The "0" position of the direction handle 1 is also the middle point position, and the direction handle 1 is in the vertical state at this time. The direction handle 1 is rotatable and has a forward position and a backward position, which is common knowledge in the field and is not a side point of the present invention.

The left side of the traction handle drum body 4 is provided with a locking groove 41, the locking groove 41 is a blind hole, when the traction handle 2 is in the '0' position, the locking plug of the locking rod 7 is inserted into the locking groove 41, and the locking plug can be separated from the locking groove 41 after the roller 6 is separated from the jacking of the boss 31.

The structural composition of the double-handle gear interlocking device is introduced, and the working principle of the double-handle gear interlocking device is explained as follows:

as shown in fig. 2 and 3, the top of the boss 31 on the handle drum 3 pushes up the roller 6 at the left end of the locking lever 7, the locking lever 7 is forced to move rightwards, the spring 8 is compressed, the locking plug at the right end of the locking lever 7 is inserted into the locking groove 41 of the traction handle drum 4, and the traction handle 2 is restrained from rotating. When the direction handle 1 is pushed forwards or backwards, as shown in fig. 6, the top of the boss 31 of the direction handle drum body 3 moves out of the roller 6, the locking rod 7 slides down along the slope surface of the boss 31 under the action of the spring 8, the locking plug at the right end is pulled out of the locking groove 41 of the traction handle drum body 4 and retracts into the guide sleeve 5, and at the moment, the constraint of the traction handle 2 is released, and the direction handle can be freely pushed forwards and backwards to perform traction or braking operation. Once the traction handle 2 is rotated to leave the position of "0", that is, the locking groove 41 is staggered with the locking rod 7, since there is no other locking groove or recess on the traction handle drum 4 for the locking plug of the locking rod 7 to insert, and the gap between the locking plug and the traction handle drum 4 is small, it is not enough to make the roller 6 on the left side of the locking rod 7 reach the top of the boss 31, so that the direction handle 1 cannot be rotated and locked, and further, no signal logic error occurs.

The utility model discloses a double handle keeps off position interlock utilizes the cooperation of locking lever, gyro wheel, boss, several parts in locking groove, has realized direction handle and traction handle's mechanical interlocking, and the mechanism design is simpler, ingenious moreover, has not only practiced thrift manufacturing cost, has reduced the shared volume of device under the mesa moreover.
