The tower arm 20 is at a fixed mounting position (the raising angle can be set as required to adjust the parachute jumping height) when in use; the hoisting power devices 80 are two in number, and may specifically include a hoisting motor 81, a hoisting shaft 82 in transmission connection with the hoisting motor, and a hoisting cable 83 wound around the hoisting shaft. The outer end of the hoisting cable is fixed at the position of the tower arm close to the front end. In the present embodiment, the length of the tower arm 20 is greater than the height from the ground installation position to the hinge of the main tower 10 and the tower arm 20, and in the present embodiment, the traction mechanism 30 is provided at the front end of the tower arm 20 to maximally utilize the height formed by the tower arm in the inclined direction. The hoisting power device 80 has the hoisting cable in a locked state in a state that the tower arm is fixed, and can play a role in safety protection of the second layer, namely, the situation that the pull rod is broken, and the hoisting cable can play a role in pulling the tower arm.

As a more specific structure, refer to the illustration of fig. 2A to 2C, which further includes a rotating part 84 disposed between the tower arm 20 and the main tower 10, and a rotating power mechanism for driving the tower arm to horizontally rotate to a desired orientation, and includes a rotating motor 85, and an external gear 851 drivingly coupled to the rotating motor.

As a more preferable embodiment, in order to safely place the pull rod during the process of ascending installation and descending placement of the tower arm, the outer end of the pull rod is hinged with the upper side of the tower arm, the inner end of the pull rod is in sliding connection (or rolling connection) with the side of the upper part 101 of the main tower 10, and ascending and descending power can be provided by the hoisting power device at the same side (a small reel with a smaller diameter is connected in series with the output shaft of the hoisting motor, and a small steel cable of the small reel is connected with the inner end of the pull rod). The inner end of the pull rod also rises or falls simultaneously in the rising or falling process of the tower arm (the length of the pull rod must be larger than the connecting length of the tower arm, the connecting length of the tower arm refers to the distance from the hinged point of the tower arm and the main tower to the hinged point of the tower arm and the pull rod), and the pull rod is fixedly installed by using high-strength fasteners such as bolts and the like only when the pull rod is in a working state. The fixed installation of the inner end of the pull rod can be manually installed (manually operated by an operator climbing up), and can also be completed by an actuating element of an electric control system. For example, the sliding connection between the inner end of the pull rod and the side of the upper part of the main tower adopts a high-strength slide rail (or the rolling connection adopts a high-strength wheel rail), and when the tower arm needs to be lifted or lowered, the slide block (or the roller seat) arranged at the inner end of the pull rod provides lifting or lowering power through a small steel cable so as to freely move on the slide rail (or freely roll on the wheel rail). When the tower arm is raised to a specified height, the electric control type transverse lock pin arranged on the high-strength slide rail (or the high-strength wheel rail) loses power and extends into a lock hole (the lock hole can be one or more than two) arranged on the slide block (or the roller seat), and the fixed installation of the pull rod and the upper part of the main tower is completed. When the transverse locking pins are arranged at a plurality of positions, a plurality of uplifting angles of the tower arm can be set.
