The invention provides a band-knife stitching instrument with an indicating device. The band-knife stitching instrument comprises a nail pushing plate and a jaw clamping plate and further comprises the indicating device which is fixed on the jaw clamping plate, wherein the indicating device comprises a fixed seat, a gear, a driving module, a stopping module and an indicating wheel; before the band-knife stitching instrument is used, the stopping module is not in contact with the gear; after the band-knife stitching instrument is closed, the driving module advances with the nail pushing plate and triggers the stopping module, so that the stopping module is in contact with the gear to stop the gear from rotating in a direction reverse to the rotation direction of the gear under the driving module; in the firing process of the band-knife stitching instrument, the gear is driven to rotate by the driving module; after once firing is finished, the driving module returns to a closing position with the nail pushing plate; and during refiring, the driving module advances again with the nail pushing plate and drives the gear to rotate.

The invention relates to a tent, in particular to a prestress support cable mesh tent comprising a tarpaulin, a prestress support cable mesh, spring telescopic rods and a rod placing device, wherein the prestress support cable mesh comprises a chord cable, a cable mesh and a main cable; axes of the main cable are mutually crossed; the chord cable alternately penetrates through a mesh cable of thecable mesh by the main cable and intersected with nodes knitted by the cable mesh; the cable mesh and the main cable are knitted together by the chord cable; the upper ends of the spring telescopic rods are connected with the main cable of the prestress support cable mesh, and the lower ends of the spring telescopic rods are installed on the rod placing device; the prestress support cable mesh obtains prestress by the spring telescopic rods after elastic deformation to drive a tent top comprising the prestress support cable mesh and the tarpaulin to support; the tarpaulin is surrounded at theperiphery of all spring telescopic rods and respectively connected to the spring telescopic rods so as to form the prestress support cable mesh tent. The tent has simple use structure, rapid unfoldingand folding, light weight, high strength, large span and favorable protecting performance and saves materials for manufacturing the tent.

The present invention opens a locking device. By virtue of the forward action it inserts the locking component 128 to the locking device 107a on the side of the holding part 109 so as to prevent the drawing of the storing box 111; by virtue of the back action it deviate the locking component 128 from the locking part 107a to allow the drawing out the storing box 111. Using the plate spring 129 set between the locking component 128 and the main body 113, it pushes the locking part 128 in the direction of inserting the locking part 107a. When it reaches the time that the holding part 109 is drawing out of the storing box 111, pull out the main body of the action bar which is supported by the axis and rotate at the outside of the box bulk 113 with finger to make the holding part 133b rotate, so that the locking component 128 resists to the push force of the plate spring 129 and moves to the direction which is opposite from the pushing direction and divorces from the locking part 107a. Thereby it can provide a structure-simple and cheap locking device.

The micro force control system disclosed by the invention belongs to the technical field of precision measurement. The invention is mainly composed of a control and information output module, an optical measurement module and a micro force generation module. The control and information output module is used for measuring optical measurement signals, micro force generation, calculation, control and external communication of signals. The optical measurement module is used to establish the corresponding relationship between the measured value and the calculated control value and the micro force value, and comprehensively calculate and output the data of the micro force. The micro force generation module uses the electrostatic force method, and adopts the comb structure to improve the resolution and range of the electrostatic force to obtain the micro force value. The invention can accurately determine the magnitude of the tiny force value through the interference method to accurately change the displacement of the tiny force value under various environmental conditions of the tiny force value. The invention has high adaptability and accuracy and compact structure. and value metrics.
