The inventive concept relates to a shoe enabling the adjustment of the tension of shoelaces. The shoe includes a first shoelace engaging member including left and right shoelace engaging members and a second shoelace engaging member. The first shoelace engaging member includes a first fixed member engaged to the shoe front upper and a movable member rotatably engaged to the first fixed member by means of hinge formed at first end of the movable member. The movable member includes a hole through which a shoelace passes and formed at second end of the movable member. The second shoelace engaging member is disposed between the left and right shoelace engaging members. The second shoelace engaging member includes a second fixed member disposed on a tongue and a second movable member rotatably engaged to the second fixed member by means of a main hinge.

A canopy assembly includes a canopy fabric, a plurality of tightening wires, and a fastening arrangement. The fastening arrangement includes a plurality of tension adjustment units. Each of the tension adjustment units includes a supporting frame, a ratchet gear, a main shaft connected to the ratchet gear and rotatably connected to the supporting frame, and a resilient locking member mounted on the supporting frame to move between a locked position and an unlocked position. In the locked position, the resilient locking member is pivotally moved to engage with the ratchet gear so as to limit the ratchet gear to incrementally rotate in one predetermined direction with respect to the supporting frame, When the resilient locking member is in the unlocked position, the resilient locking member is pivotally moved to disengage from the ratchet gear so as to allow the ratchet gear to freely rotate with respect to the supporting frame.

The invention relates to a hand sanding tool (10) with a sanding sheet (20), covering the underside (18) of the sanding plate and with clamping means (22, 24, 30), for fixing the sanding sheet (20) to the sanding plate (14), whereby the clamping means (22, 24, 30) comprise clamping bodies (24), pressing on the ends (21) of the sanding sheet, characterised in that the clamping body may be freely rotated about an eccentric axis (28) and the pivot axis (28) is arranged essentially perpendicularly above a concave curved retaining surface (22).

Device for carrying a replacement safety valve in a well tube, with a straddle structure for placement inside a damaged “Down Hole Safety Valve” nipple seal area. It is comprising a pair of sealing assemblies (15, 16) to be activated upon setting of the device to seal said nipple seal area, and a locking dog assembly (17) for locking the device in the well tube, said elements being carried by a tubular mandrel (12). At least one of the sealing assemblies (15, 16) comprises a expandable element (22; 34) being activated by a pair of annular press elements (19, 20).

A method of processing a wafer having a plurality of devices partitioned by division lines, including attaching the wafer to an adhesive tape supported by a first annular frame, dividing the wafer along the division lines into a plurality of dies, and placing the wafer (and the adhesive tape) on a support surface of a support member before or after dividing the wafer, wherein an outer diameter of the support member in the plane of the support surface is smaller than an inner diameter of the first annular frame. The method also includes moving the first annular frame and at least a peripheral part of the support member relative to each other to radially expand the adhesive tape, thereby moving the dies away from each other, and attaching a second annular frame to a portion of the expanded adhesive tape arranged at the peripheral part of the support member.

An automatic adhesive pasting device structurally comprises a suction nozzle and a taking platform, wherein the suction nozzle and the taking platform are arranged on a rack, a first tensioning roller is arranged above the taking platform, a second tensioning roller is arranged below the taking platform, adhesive tape is pre-tightened to the taking platform through the first tensioning roller and the second tensioning roller, the taking platform is provided with a taking position, the suction nozzle sucks foam at the taking position under the action of external driving force and is in a static state at the moment, and then the taking platform moves in the direction far from the suction nozzle under the action of the external driving force to make the adhesive tape aligned with the suction nozzle in a suspended state; meanwhile, the second tensioning roller drives the adhesive tape on the back of the taking platform to move along with the taking platform so that the adhesive tape in the suspended state can move towards the back of the taking platform and be stripped off from the foam to be taken. According to the automatic adhesive pasting device, in the taking process, the situation that the foam drives the adhesive tape to move can be effectively prevented, and the adhesive tape is made to keep constant tension all the time; as a result, the production efficiency can be improved, and a good adhesive pasting effect is ensured.

The invention discloses a spiral tensioning device of an air conditioning box access door. The access door is hinged with a heat-preservation plate of an air conditioner through hinges; the edge of a corresponding access door is provided with an inner door frame; the inner side face of the access door is rotatably provided with a connecting rod through a rotating shaft; the access door is provided with a first limiting sleeve and a second limiting sleeve corresponding the two ends of the connecting rod; the outer side face of the access door is provided with a sliding pin component comprisinga fixed part which is fixed on the access door and a sliding part which can slide along the fixed part; the sliding part can rotate in the direction perpendicular to the surface of the access door; athird limiting sleeve is arranged on the outer side of the heat-preservation plate; the sliding part is inserted into the third limiting sleeve; the connecting rod in the second limiting sleeve is provided with a first nut; the sliding part is provided with a second nut; the access door is provided with a through hole which is perpendicular to the surface of the access door; and a bolt is matchedin the second nut, and is matched in the first nut after passing through the through hole, so that the access door is tensioned on the inner door frame. The spiral tensioning device has a simple structure, is easy to implement, is reliable in tensioning effect and is suitable for popularization and use.
